It seems to me that the pots are of an Metric Style. Split 6mm post. 8mm Bushing. The two 500k pots do not seam to be a problem. The two 150k pots are stumping me. Anybody have any advice on where to find these guys,or any ideas on substitutions/modifications. I'm really not wanting to drill the guitar, just really trying to keep the guitar as stock as possible. Thanks. If any of the above information is wrong please correct. Again. Thanks.

Sometimes they come up on bay when someone guts them for cash but you have to watch closely. You might try Dr Dave from this forum. He has a web site and does come up on Electra parts. He has helped me many times in getting items for my guitars.

Sounds like you have an Mpc, what is it you are trying to do with it? The 150k pots are for the effects control and I forget the reason for them being used, but that's what you have to use. Mcbrat or Thorny might have an idea where to get new ones if you need some. There are threads here on the pots for MPCs and the wiring.

Yes it is an MPC. The 150K pots are used to control the effects. As far as what I'am doing is replacing the old dirty/corroded pots and jack. Bringing the old guitar back to snuff. I will say that those old Electras were quality made, The neck is still fantastic, the feel of is great. Thanks for any leads and ideas, keep them coming. I will repost how this all worked out. I found the 500k pots at Steward/McDonald. The pots were made by Alpha.

The last 150K pots I found that worked I got from Amazon. They were physically smaller sized ones, but functionally identical and took the same knurled import knobs too. I checked back, and can't find them. But keep looking, you may find some. I see some other styles there now but can't tell if the size is too big and if the knob is the same or not. Also use google and ebay to search. Keep looking. Good luck.
